Abstract
Apparatus for cutting straps wound on a bale of material in which the bale of material is brought into contact with a cutter blade which is forcibly retracted against the action of a spring whereafter the cutter element is released under the pressure of the compressed spring and is thrust forwardly against the bale to cut the straps on the bale.
Claims21
Bale cutting apparatus for cutting straps wound on a bale of material, said apparatus comprising reciprocable cutter means having an initial position and being movable between a retracted inoperative position and an extended operative position, and means operative in response to contact of a bale with the cutter means in said initial position for retracting the cutter means to its retracted position and for thereafter propelling the cutter means to its extended position to cut the straps on the bale.
Bale cutting apparatus for cutting straps wound on a bale of material, said apparatus comprising cutter means having a retracted inoperative position and an extended operative position, energy storage means opposing movement of the cutter means from the extended to the retracted position, power drive means for moving said cutter means from the extended position to the retracted position in opposition to the energy storage means, and control means activated by contact of a bale with the cutter means to energize the power drive means to move the cutter means to said retracted position, said power drive means including release means for releasing the power drive means from the cutter means in said retracted position to cause said cutter means to move to said extended position under the thrust of said energy storage means for severing straps wound on the bale.
